    Trying to determine proper engine/ trans/ prop pairing

    the only way to size props....... is mash the throttle at WOT, then report the RPMs and speed. you need to prop to get the motors to the upper end of the WOT RPM window for a carbureted SBC or BBC, that is in the 4600-4800 RPM range.

    opinions....

    manifolds on a low hour motor means the other ones rotted from sitting. the salt trails suggest there is internal corrosion in the drive, hence the bravoitus comment. do some reading on bravoitus. https://www.google.com/search?-b-1-d&q=bravoitis

    What gas do I use in my boat???

    absolutely no benefit to you, however your wallet is lighter, so the oil companies make more money. to get a benefit from 93 octane, you need much much higher compression than you have in that low power output 2.5 liter Chevy nova motor.
